     View Summary

    This study aimed to investigate how sexual consent is depicted in sex comics published in Japan. Twenty best-selling comics from 2010 and 2020 were set as objects of analysis and separated into 277 scenes. A codebook developed after five rounds of trials was utilized by four coders to code the materials. First, the results showed that explicit communication was not rare: among all materials, 39.9-57.3% of scenes were initiated by an explicit approach, while only 5.2-19.4% of scenes were coded as depicting non-explicit initiation. Further, as for the act of gatekeeper, 21.6-35.5% and 6.5-9.7% of scenes depicted explicit consent and refusal, while 20.3-28.2% of scenes were coded as expressing non-explicit consent/refusal. Second, in the comparison between 2010 and 2020, there were fewer scenes in which more than three characters were involved and sexual acts were initiated by non-explicit forms in 2020. Contrastingly, there were more scenes in which sexual acts were initiated by assault or intimidation. Based on these findings, social implications and future research orientations are discussed.

  • Judges' evaluation of psychological findings::Empirical research on criminal judgment

    Fukushima Yui, Mukai Tomoya, Aizawa Ikuo, Iriyama Shigeru

    The Japanese journal of psychology   92 ( 4 ) 278 - 286  2021.07  [Refereed]

    Authorship:Lead author

     View Summary

    <p>An increasing number of criminal court cases have seen psychologists present their findings as evidence after conducting experiments and surveys to evaluate the credibility of witnesses' statements and suspects' false confessions. Courts, however, have not always welcomed psychological findings. As some courts have not affirmed the value of these findings in some well-known cases, some researchers suggest that courts have little trust in psychological findings. To consider the validity of this suggestion, we conducted a quantitative investigation of the courts' decision-making processes when presented with psychological findings in 50 criminal cases. The results showed that most of the courts' judgments involving psychological findings were negative, and that the reasoning for the judgments could be classified into nine categories. The most common reasons were related to the methodological flaws used to derive the psychological findings.</p>

    Fukushima Yui, Jordan Kayla, Garry Maryanne, Hanyu Kazunori

    Proceedings of the Japanese Society for Cognitive Psychology   2021   67 - 67  2022

     View Summary

    The post-identification feedback effect (PIFE) refers to the distortion of eyewitness memory after receiving feedback implying their identification was either correct or incorrect. Although previous studies indicate that feedback influences eyewitness memory, it is not clear if this distorted memory will alter eyewitness behavior. In this study, we explored whether people who received confirming feedback were more likely to provide experimental data as evidence for an ongoing trial. Immediately after making identification, participants were given either confirming feedback (Good, you identified the suspect), disconfirming feedback (Actually, the suspect was number_), or no feedback. After receiving this feedback, all participants answered dependent measures. Our results replicated the PIFE. However, participants who were given confirming feedback were not significantly more likely to provide experimental data than the other groups.

  • Modeling Determinants of Individual Punitiveness in a Late Modern Perspective: Data from Japan

    Tomoya Mukai, Yui Fukushima, Shigeru Iriyama, Ikuo Aizawa

    ASIAN JOURNAL OF CRIMINOLOGY   16 ( 4 ) 337 - 355  2021.01

     View Summary

    There is a growing trend to both theoretically and empirically explain public punitiveness from a general social theory of late modernity. Yet, research which has tested the generalizability of this perspective regarding societies other than Western ones remains rare. Relying on a theoretical perspective and empirical findings, this study aimed to explore whether the hypothetical model, which assumes that abstract late modern anxieties (economic anxiety and identity anxiety) affect punitiveness via more tangible fears and negative attitudes toward others in terms of fear of crime, xenophobic attitudes, and social dominance orientation (SDO). The study considered whether this model can be applied to Japanese society, which is experiencing drastic social, economic, and political transformations. Accordingly, data from a nationwide Japanese sample was analyzed through structural equation modeling (SEM). The results revealed that all of the hypothesized paths had significant relations, except for a path between xenophobic attitudes and fear of crime, which generally supported the hypothetical model. Moreover, it was shown that all of the variables have a significant total effect on punitiveness. The results were discussed in light of the social circumstances of Japan and recommendations for further international comparative research were made.

  • The effect of a suggestive interviewer on the performance of repeated eyewitness showup identifications:A study using a DON'T KNOW option.

    JJLP   16 ( 1 ) 100 - 111  2016  [Refereed]

    Authorship:Lead author

     View Summary

    The present study examined whether providing a DON&#039;T KNOW option reduce the influence of a suggestiveinterviewer on the performance of eyewitnesses in repeated showup identification procedures. Fifty-seven participantseye-witnessed a staged event in which a man took a wallet from an unattended bag; they were laterinterviewed twice. Each interview included two showup identification procedures: one with a suggestive interviewerand the other with a non-suggestive interviewer. In the showup identification procedure, the participantswere shown pictures depicting a man and choose one of the three responses: YES, NO, or DON&#039;TKNOW. The person who took the wallet was never in the picture shown, so a YES response was an incorrectidentification (i.e. false alarm), and NO was a correct rejection. In the suggestive condition, the participantschose the YES significantly more often than NO and DON&#039;T KNOW, while in the non-suggestive condition,NO and DON&#039;T KNOW were significantly more frequent than YES. This indicates that providing a DON&#039;TKNOW option does not reduce the influence of a suggestive interviewer. Furthermore, the participants in thesuggestive condition tended to maintain their first identification response more often than the participants inthe non-suggestive condition. The results were interpreted according to the conformity theory of memory.

  • Examination of the postidentification-feedback effect that influences eyewitness testimony

    FUKUSHIMA Yui, ITSUKUSHIMA Yukio

    JJLP   14 ( 1 ) 98 - 106  2014  [Refereed]

    Authorship:Lead author

     View Summary

    Wells and Bradfield (1998) reported that witnesses who received confirming feedback (&quot;Good, you identified the suspect&quot;) tended to show (a) a clearer view of the crime and crime scene, (b) higher quality memory, (c) high confidence in recounting events, and (d) a willingness to testify at trial. These phenomena are called the &quot;postidentification-feedback effect (PIFE).&quot; We conducted two experiments to investigate whether PIFE could be replicated (Experiment 1) and to observe the aftereffects using a semistructured interview (Experiment 2). In both experiments, the PIFE were confirmed. In addition, we tried to interpret these results in terms of the selective cue integration framework (Charman, Carlucci, Vallano, &amp; Gregory, 2010) in order to confirm the correlation. We found that the reports from our participants supported the framework. However, it was suggested that the framework could not explain the influence of pressure imposed by the interviewer. Further studies are needed to verify the other factors that affect the PIFE.
